A kind reader pointed out that my troubled, leaf dropping rubber tree, Ficus Elastica Sylvia, is notoriously difficult in indoor homes. He eventually found a good home with a greenhouse for his. Researching my rubber tree online, I just discovered that the rubber tree is one of the best plants for reducing indoor pollution. They do this thorugh their natural processes, transpiration and photosynthesis.
I knew that spider plants and philodendrons were good for this, but didn't know that there were so many others. Anyway, this makes me more determined to hang onto the thing, as I've been experimenting with adding more indoor greenery to my apartment, for air-quality benefits. In fact my dream is to have an indoor plant wall. And a fountain. And a bigger apartment.
Anyway, in the meantime, I find there is a book written on the subject by a NASA scientist, B. C. Wolverton. It's definitely on my list to check out. It has a five star rating on Amazon. See the book on Amazon here.
Another in depth article (by Alys Fowler from the Guardian) about this subject is here. Among her recommendations are keeping a Christmas Cactus by your bed as they are one of the few plants that release oxygen at night. She also mentions that areca palms transpire a litre of water every 24 hours.
